Australian Central Standard Time Zone - ACST

Australian Central Standard Time or ACST has a UTC offset of +9:30. This means that the time zone is 9 and a half hours ahead of Coordinated Universal Time. The time zone is primarily observed by territories and states in Australia during the winter months when Daylight Saving is inactive. As soon as Daylight Saving begins – during the summer – the affected territories switch to Australian Central Daylight Time or ACDT.

Australian Central Standard Time is what is referred to as a non-standard half-hour time zone. This means there is a 30 minute difference in local time from the actual one-hour time zone interval you’d usually see if traditional time standards were used.
